project/EsmScriptFuncs.cpp defines short versions of the macros for the script functions and you can’t tell what the names mean at a glance. For an example, it defines 0 as VN and ESMSCR_FUNC_BYTE as VB. These should probably be changed to use the long form
Edit:
Looks like I should be done with the bulk of the whitespace reformatting sometime next week or the following week. I know for a fact I missed a few bits here and there but I’ll get those as I go through and do the other cleanup tasks.
